OEX Alternator 12V 170A Valeo Style VXA045

The OEX Alternator VXA045 is a 12V, 170A unit built in Valeo style for applications that require the correct electrical output and mounting pattern. It is a new alternator, supplied each, with an internal regulator and a 6 groove pulley. The listed part number is VXA045, which is the most practical reference to confirm before ordering.

This alternator is specified with a pulley outside diameter of 53mm, inside mounting legs of 76mm, a pivot hole diameter of 11/M10x1.5, and a mount centre to centre measurement of 125mm. Those dimensions matter when matching the unit to the vehicle and the original alternator arrangement, especially where bracket spacing and pulley alignment need to be correct.

OEX lists this unit as suited to Valeo style applications and supports it with a 3 year passenger / 1 year commercial warranty. The alternator weighs 7.42kg, which is useful to know when comparing like-for-like units and handling the part during installation.

Application and Buying Notes

Before ordering, confirm the existing alternator is the same 12V, 170A Valeo style unit and check the part number VXA045 if it is available on the vehicle or old component. Alternators can look similar from the front, but pulley type, bracket spacing, and regulator style need to match for a proper installation.

The key measurements here are the 76mm inside mounting legs, 125mm mount centre to centre, 11/M10x1.5 pivot hole diameter, 11mm adjusting hole diameter, and 53mm pulley outside diameter. If any of these differ from the original unit, the alternator may not align correctly with the belt drive or mounting brackets.

The 6 groove pulley is another important point to verify. Belt profile must suit the vehicle setup, and the alternator should be checked against the existing pulley before purchase. The internal regulator configuration also needs to match the vehicle’s charging system arrangement.

This unit is listed for Valeo style applications and the fitment preview supplied includes BMW 5, BMW X5, and BMW X6 applications across multiple model years. Even so, those details should be treated as a guide only until the part number and physical measurements are checked against the vehicle currently fitted with the alternator.

At 7.42kg, this is a substantial rotating electrical component and should be handled with care during inspection and installation. If the vehicle has had prior repairs, it is worth confirming the belt line, plug arrangement, and mounting points on the existing unit before committing to the replacement.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number VXA045 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Alternator 12V 170A Valeo Style. Part number VXA045 should be checked first. Listed voltage is 12. Listed output rating is 170. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number VXA045, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 170 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 5, BMW 5 2005, BMW 5 2006, BMW 5 2007. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using the part number VXA045, the Valeo style application, and the listed mounting and pulley measurements before purchase. Do not rely on appearance alone when matching alternators.
